Third, the initial stage of the disease is to use 40% ethyl phosphorus aluminum wettable powder 400 ~ 600 times liquid, or 25% frosting 400 ~ 600 times liquid sprayed beads; also can be used to replenish roots 400 times liquid, 600 times liquid spray plant Use 22% frost urea zinc wettable powder 500 ~ 650 times liquid, spray once every 7 days, even spray 2 ~ 3 times; 50% carbendazim wettable powder 500 ~ 800 times liquid spray; 64% antivirus矾500 times liquid spray.

Downy mildew: Mainly harmful to tomatoes, eggplant, pepper, cucumber and so on.
